President Rouhani told the crowd: "We have repeatedly declared that strengthening the defensive prowess of Iran’s Armed Forces is only aimed at defending the country and will never be used against another country.

“Striking a regional balance and maintaining the defensive and deterrent power of a pivotal country like Iran, which has endangered big powers’ interests through its great Islamic Revolution and is conveying the message of justice and freedom to the world, are necessary."

But, the Iranian president noted "intervention and the cancerous tumor of Israel" as a source of concern and insecurity in the Middle East.
